Travel Technology - Prepaid GSM suggestions in Finland?

Any suggestions on a prepaid network to use while in Finland for about 5 days. Strictly Helsinki. GPRS would be nice but isnt necessary. People on Howard forums dont seem to go to Finland and prepaidgsm.net show several options but unfortunately some of their links to little things like calling rates are in Finnish. Thanks for any suggestions.

dna (http://www.dnafinland.fi/english/yksityisille/liittymat_ja_palvelut/gsm/dna_prepaid.shtml) offers prepaid SIMs as does Sonera ("Easy"), and Elisa (Kolumbus?).

I found this Q & A...

Note that international calls have separate pricing. There are several operators that you can choose between by using a special prefix when calling. Fees depend on which country you are calling. If using the + or 00 prefix, your call will be handled by the default international operator for your prepaid package.

The ubiquitous R Kioski cornerstores sell all the above prepaid packages.

Some operators require you to activate GPRS service by sending an SMS to their service number or calling their customer service.
